The Kansas City Chiefs play the Houston Texans this week so it makes me a little nervous to read this article from The MMQB on how JJ Watt can line up anywhere he wants on the field in the Texans defense. Go ahead and read the article for the comparisons to Lawrence Taylor, who once played for the guy coaching the Texans defense: Romeo Crennel (remember him?).
Watt has earned enough trust from the coaching staff that he has the freedom to line up and do what he wants on a particular play based on what the opposing offense is doing. The article states that Watt will find your weakness and relentlessly attack it.
That means that every one of the Chiefs offensive linemen need to be prepared, especially the right side of the line. The Chiefs have two first year starters in rookie center Mitch Morse and right guard Laurent Duvernay-Tardif. Eric Fisher is moving back to the right side where he is practicing at right tackle for the first time since his rookie season. Watt will likely try to exploit that side. The Chiefs coaching staff has to be agile enough to quickly adapt and change what they're doing based on how Watt is playing them.
The Chiefs offensive line will require blocking assistance from the running backs. This could affect who gets snaps among the Chiefs backs. Jamaal Charles is the Chiefs best pass blocking back and the best receiving back so expect to see plenty of him as you expected. Knile Davis is not as good pass blocking so I don't expect to see him on many passing downs (which makes the Chiefs one dimensional when he comes which means he probably won't see many snaps). Charcandrick West is better as a pass blocker but asking a young dude with little NFL experience to block Brian Cushing off the edge while Watt and Vince Wilfork penetrate the middle is a daunting task.
In short, it takes a village to block JJ Watt; not just one person.
